问题描述

[HttpPost]
        [ValidateAntiForgeryToken]
        public async Task Create([Bind]Employee employee)
        {
            if (ModelState.IsValid)
            {
                var files = HttpContext.Request.Form.Files;
                foreach (var Image in files)
                {
                    if (Image != null && Image.Length > 0)
                    {
                        var file = Image;

                        var uploads = Path.Combine(_appEnvironment.WebRootPath, "uploads\\img");
                        if (file.Length > 0)
                        {
                            var fileName = Guid.NewGuid().ToString().Replace("-", "") + Path.GetExtension(file.FileName);
                            using (var fileStream = new FileStream(Path.Combine(uploads, fileName), FileMode.Create))
                            {
                                await file.CopyToAsync(fileStream);
                                employee.ImageName = fileName;
                            }

                        }
                    }
                }
                db.Employees.Add(employee);
                db.SaveChanges();
                return RedirectToAction("Edit", new { id = employee.Id,name=employee.FirstName});
             }
        else
        {
            var errors = ModelState.Values.SelectMany(v => v.Errors);
        }
            return View(employee);

        }

推荐答案

您好朋友使用以下功能它可能会帮助您out：

Hi friend use below function it may help you out :

public static string MapPathReverse(string fullServerPath)
    {            
        return @"~\" + fullServerPath.Replace(HttpContext.Current.Request.PhysicalApplicationPath,String.Empty);
    }

如果它没有帮助只是让我知道我会解决它。

if it does not help just do let me know i will fix it.
